[0002] The automatic tobacco fermentation box is a set of equipment designed for laboratory pilot production lines that can achieve continuous fermentation. It includes a box body and a multi-layer conveyor belt arranged in the box body. By controlling the temperature and humidity values ​​in the box body and the transmission speed of the multi-layer conveyor belt, the tobacco material can be continuously fermented in the fermentation box.

[0003] Since the fermentation environment is closed, the space environment needs to be cleaned after the fermentation is completed, otherwise bacteria will easily breed.

[0004] In large-scale production lines, cleaning is mainly done manually, and the equipment space is large and the operability is strong. However, in laboratory-based automatic fermentation boxes, the operating space is insufficient, manual operation is difficult, and it is easy to leave sanitary blind spots, so automated cleaning methods are needed.

[0005] In addition, tobacco fermentation has high requirements for hygiene and safety, and usually adopts food safety standards, so general equipment cleaning products cannot be used.

[0006] Taking into account the particularity of the tobacco fermentation environment, the main thing that needs to be killed is the miscellaneous bacteria, and the remaining debris is cleaned up. Therefore, it is necessary to design a cleaning system that can meet the requirements of miscellaneous bacteria killing and debris cleaning while meeting the requirements of hygiene and safety.

[0007] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

[0025] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0026] like Figure 1-Figure 3 As shown, a tobacco automatic fermentation box cleaning system includes a water tank 1, an ozone generator 2, a flushing water pump 3, a flushing component and an airflow circulation component.

[0027] The outlet of the ozone generator 2 is divided into two paths, one of which is connected to the air circulation component and is provided with a first stop valve 21. The circulating air inlet pipeline 4 and the circulating air return pipeline 5 of the air circulation component cooperate with the circulating fan 6 to realize the introduction and circulation of ozone into the fermentation box 7; the other path is connected to the ozone inlet of the water tank 1 and is provided with a second stop valve 22, and cooperates with the water tank 1 to prepare ozone water.

[0028] A tap water inlet and an ozone inlet are arranged at the top of the water tank 1, and an ozone water outlet is arranged at the bottom of the water tank. The ozone water outlet at the bottom of the water tank is connected to a flushing component through a flushing water pump 3 and a third stop valve 23, so as to introduce ozone water into the fermentation box 7.

[0029] Specifically, the flushing component includes a flushing pipeline, a cleaning pump, a branch control valve 11 and several groups of nozzles 12. The several groups of nozzles 12 are arranged in the fermentation box 7 and installed at the height corresponding to the conveyor belt in the fermentation box 7. The end of the flushing pipeline is divided into several branches and connected to each group of nozzles 12. The branch control valve 11 is used to control the on and off of each branch, and the cleaning pump is used to provide power for the flushing pipeline.

[0030] The outlet of the circulating air inlet pipeline is distributed at the bottom end of the fermentation box 7, and the inlet of the circulating air return pipeline is distributed at the top end of the fermentation box 7.

[0031] Technical principle description:

[0032] One path of the ozone generator 2 is connected to the air circulation component, and the prepared ozone is directly introduced into the fermentation box 7, and the environment in the fermentation box is disinfected and sterilized through circulation;

[0033] The other path enters the water tank 1 to be prepared into ozone water, which is then introduced into the fermentation box 7 through the flushing water pump 3 to clean the conveyor belt.

[0034] In a preferred embodiment, in order to enhance the preparation efficiency of ozone water, the pipeline on the outlet side of the flushing water pump 3 is connected to the ozone inlet at the top of the water tank 1 through a reflux valve 24 and a reflux pipeline 8, and the other route of the ozone generator 2 is connected to the reflux pipeline 8 and a first gas-liquid mixer 25 is installed at the connection point, i.e., the three-way position.

[0035] Technical principle:

[0036] When the flushing component is closed, the flushing water pump 3 realizes water circulation in the water tank 1 through the reflux valve 24 and the reflux pipeline 8. During the circulation process, the water is merged with the introduced ozone through the first gas-liquid mixer 25 installed at the three-way position to improve the efficiency of ozone water preparation.

[0037] In a more preferred embodiment, in order to further improve the ozone production efficiency, an exhaust port is provided at the top of the water tank 1, and the exhaust port is connected to the reflux pipeline 8 through an exhaust valve 26 and an exhaust pipe, and a second gas-liquid mixer 27 is provided at the connection.

[0038] Technical principle:

[0039] The part of the ozone that has not been fused and has entered the water tank 1 is discharged from the exhaust port, then enters the return pipe 8, and is secondary fused through the second gas-liquid mixer 27, thereby further improving the efficiency of ozone water preparation.

[0040] In order to ensure the requirements of the ozone water preparation environment, a liquid level sensor is installed in the water tank 1 so as to prepare ozone water that meets the requirements.

[0041] In other embodiments, a fresh air component is also included, which includes a fresh air duct, an air filter 9 and a fourth stop valve 28. One end of the fresh air duct is connected to the atmosphere, and the other end is connected to the air flow circulation component, which is used to replenish fresh air into the fermentation box 7. Generally, fresh air is replenished after the ozone cleaning is completed, and the residual ozone is discharged from the fermentation box to avoid affecting the fermentation process and prepare for the next round of fermentation.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
